GASOLENE-TANK.

Application flied March 25,

This invention relates to improvements in gasolene tanks of that kind which are employed for supplying gasolene by air pressure to a lamp or lamps located at a distance from the tank; and it consists in the com struction, combination and arrangement of devices hereinafter described and claimed.

The object of my invention is to combine with the gasolene feed tube of the tank, which leads therefrom to the burner or burners and which on account of its length and its ex osed osition is liable to become accidenta ly bro ken, and to hence discharge the gasolene contents of the can under atrnos pheric pressure at the said broken point, an air or vent tube which is coextensivewith the said gasolene discharge tube, is more i frangible than said gasolene discharge tube and is also less refractory than such gasolene discharge tube, so that before said gasolene discharge tube will break under stress or heat ap lied thereto, said air or vent tube will brea and hence afford vent for the coinpressed air in said tank, and revent the escape of the gasolene through t e gas'olene discharge tube or feed tube, and thereby obviate danger of fire in theeyent that the gasolene tube should become'b'roken, and prevent gasolene from being discharged from the gasolene tank to the fire in a building in the event that such gasolene tube should break or. become unsoldered by the action of heat.

In the accompanying drawings,Figure 1 is a vertical sectional view of a gasolene tank provided with a frangible air or vent tube, embodying my invention; Fig. 2 is a detail sectional view of: a portion of the gasolene tube and a portion of said frangible air or .vent tube.

The gasolene tank 1 is here shown as of-the usual construction, 2 being the 'gasolene supply tube, 3 the valve which controls the pas sage of the gasolene from the lower ortion Specification oi Letters'latent.

the burner or burners, 5 being-the pump to com re'ss air in the tank abovethe body of gaso ene therein, and 6 being the gage to in-. dicate the pressure of the air. v 1

Usually the gasolene tube 'iis made of brass. The same is of small diameter, gen-Y erally about one-eighth of an inch, and the same is of considerable length, is necessarily exposed'and is liable to be broken casually, in which event gasolen'e would be discharged.-

a from the tank under the pressure of the therein through the'said tube at the brokelil point of the latter, and danger of firewould result. To obviate this danger and to also prevent gasolene from being fed to a fire already started in a building by the breaking of the tube 4., I provide an air or vent tube 7, which is disposed on one side of the gasolene tube a in contact therewith and extends throughout the entire length thereof. The end of the said air or vent tube which is most remote from the" tank is closed. Its innerv end communicates with the tank ata point above the level of the gasolene therein, For the pur dress of this speoifieation the inner end of t 1e said vent p'pe '7 is here'shown as extending through the oody'of the valve 3 to the upper end of the tank. I do not limit myself in this particular, as the inner end 'of' the vent or air tube may be attached to the tank at any suitable point, and by anysuit able means. I

The essential feature of my invention is that the air or vent tube is more frangible than the gasolene, tube, sothat it will break under stress before the gasol-ene tube, and

the said air or vent tube is also less refractory than the gasolene tube, so that in the event of their being exposed to heat ,.as from fire in a building, the air or gvent tubeiw'ould part under the action of the heat beforethe gasolene tube would 'b akor become burned through, and hence in either event, the coin-- pressed air would be caused to escape from the tank, and hence the gasolene would be prevented from escaping therefrom through the broken portion of the gasolene tube.-

My improved tube is preferably made in sections 8 united together by readily fusible connections 9, as of soft solder. The connections of the gasolene tube are of hard solder,

less readily fused than the connections of the air or vent tube. The said connections 9 are readily broken under stress to which the air tube, together with the gasolene tube may be subjected, and hence under such stress such air or vent tube would break before the gasolene tube would break.

In the event of a fire in the building one or more connections 9 of the air tube would be fusedbefore the gasolene tube would be injured materially, and hence the compressed air would escape from the tank.

From the foregoing description,- taken in connection with the accompanying drawing, the construction and operation of the invention will be readily understood without requiring a more extended ex lanation.

Various changes in the orm, proportion and the minor details of construction may be resorted to withoutdeparting from the principle or sacrificing any of the advantages of this invention, as defined by the'appended claims.

Having described my inventio'n,I claim: l A gasolene tank having two tubes of unequal frangibility leading therefrom, and extending substantially adjacent to each other throughout their length.

2. A gasolene tank having two tubes leading therefrom and extendin substantially adjacent to each other throug out their length, on}: of the tubes being less fusible than the ot er.

ing therefrom and extending substantially adjacent to each other throughout their length, one tube communicating with the can below the level of the oil and the other one communicating with the can above the oil and having its outer end closed.

5. A gasolene tank provided at its top with a valve, two pipes extending into the tank at the valve, the outer portions of said pipes extending substantially adjacent to each other throughout their length, and one of them being less fusible than the other, the inner end of the less fusible pipe extending below-the level of the oil and the inner end of the other pipe terminating at a point above the oil.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
